Flashing of the LCD
If the power supply for the portable VHF station drops below 10.5 V, the
display begins to flash. This flashing indicates, when operating on batte-
ries for example, that the batteries require recharging. In prac-tice the
display begins to flash in the transmit mode because this is when the po-
wer consumption is greatest. If the power supply again increases above
10.5 V, the flashing ceases.
Because the discharge curves of thebatteries are very dependant on the
type of battery, e.g. lead or nickel/cadmium accumulators, and the am-
bient temperature also influences the discharge curves, it is not possible
to state precisely how long the portable VHF station continues to be fully
functional after the LCD begins to flash.
When transmitting, the batteries can be completely discharged after a
few transmission cycles but during reception functioning is still guaran-
teed in most cases for approximately 1 to 2 hours after the flashing be-
gins.
